Definitions

  • the article is an airfoil, combustor wall or blade outer seal for a gas turbine engine.
  • Figure 6 shows the relationship of the molar volume ratio (V OX /V M ) to porosity for some example materials such that upon oxidation the volume expansion is exactly compensated by the porosity.
  • the porosity of the particles 208/308/408 could be similar to the porosities shown in Figure 6 for a given material, e.g., +/- 10% of the porosity shown in Figure 6 in some examples.
  • a slightly lower porosity, e.g., between about 0-10% less, than that shown in Figure 6 could induce compression in the barrier layer upon oxidation of the particles 208/308/408, which in turn could assist in closing cracks in the barrier layer.
  • the barrier layer and/or intermediate layer 316 can be fabricated using a slurry coating method.
  • the appropriate slurries can be prepared by mixing components, such as a porous hafnium silicide particle, silicon oxycarbide, barium-magnesium alumino-silicate, and powder of silicon dioxide or colloidal silica (Ludox) in a carrier fluid, such as water.
  • the slurries can be mixed by agitation or ball milling and the resulting slurry can be painted, dipped, sprayed or otherwise deposited onto the underlying substrate 104.
  • the slurry can then be dried at room temperature or at an elevated temperature to remove the carrier fluid.
